You can get 50$ in bonus funds, just if you will wager at least 500$ at each of the 6 different days of the whole month. As i am lowroller it is of course not very easy task for me, because wagering 500$ is not so easy task, and it is need to be done within 6 different days. Also a bit hard here that only real money bets count for this promotions, so if you for example claimed 100% bonus, and lost your real funds, then you will not get wagers count to this promo.
But i am must admit this is still very good bonus, because once casino award it - there is only 750$ wagering need to be done to withdraw this money, so it is very low 15x wagering requirements for this bonus.
In my gambling life at betat casino i received this bonus two times, because it is really not easy to wager 500$ in 6 different days for me, of course for players who can deposit something like 50-100$ in one chunk each day it is not very hard promo, but like i said, i am lowroller.
First time after receiving this bonus i lost it playing different netent slots, fill about 70% wagering requirements, but then decide to try DOA, and of course left all money there. With second this bonus i was able to withdraw 130$. Played only Thunderstruck II at 0.60 bets, and it was not so hard to complete WR, balance at peak was about 190$, but unfortunately while clearing left WR i lost a bit.
But generally this is of course good bonus, does not require anything extra from players - just wager and get this bonus. Also completing this bonus is a key to sucess at another WR promo - where you could get 100$ in bonus funds.
